実験手順

To a stirred suspension of 2′-methyl-2′,3′-dihydro-1′H-spiro[cyclopropane-1,4′-isoquinolin]-7′-amine dihydrochloride (1.90 kg, 7.27 mol, 1.09 eq.) in chloroform (19 L) at room temperature was added 5 N NaOH (3.8 L), and the mixture was stirred for 5 minutes. The chloroform layer was separated and the aqueous layer was extracted with chloroform (9.5 L). Combined chloroform layers were washed with 5% aqueous NaCl (9.5 L), then dried over anhydrous sodium sulfate (3.8 kg) for 1 hour. Sodium sulfate was filtered and washed with chloroform (3.8 L). Combined filtrate and washing were evaporated to give crude oil. Methanol (4.6 L) was added and the solution was evaporated to give 2′-methyl-2′,3′-dihydro-1′H-spiro[cyclopropane-1,4′-isoquinolin]-7′-amine (1.40 kg) as brownish crystals in crude 102% recovery.
